Generic Tasigna Information

Introduction

Tasigna (nilotinib) is an oral tyrosine‑kinase inhibitor indicated for the treatment of chronic myeloid leukaemia (CML) in adult patients. Developed by Novartis International AG, the medication inhibits the BCR‑ABL oncoprotein that drives the proliferation of malignant white‑blood cells. In Hong Kong, Tasigna is listed on the Pharmaceutical Service (P‑service) for specialist prescription and is reimbursed under the Chronic Disease Management Programme for eligible patients. Its targeted action makes it a cornerstone therapy for patients who have shown resistance or intolerance to first‑line imatinib.

What is Tasigna?

Tasigna is the trade name for the active compound nilotinib, a second‑generation BCR‑ABL tyrosine‑kinase inhibitor. The drug was the US Food and Drug Administration (FDA) in 2011 and subsequently by the Hong Kong Department of Health. It is manufactured by Novartis, a multinational pharmaceutical company with a long history of oncology research.

Although Tasigna is the brand name, generic nilotinib formulations are available worldwide. Our online pharmacy offers the generic version, providing the same therapeutic molecule at a lower cost while meeting the same quality standards required by international regulatory agencies.

How Tasigna Works

Nilotinib binds competitively to the ATP‑binding site of the BCR‑ABL protein. By occupying this pocket, it prevents phosphorylation of downstream signalling molecules that would otherwise promote uncontrolled cell division. The drug has a higher affinity for the mutated forms of BCR‑ABL (including many imatinib‑resistant mutations) than first‑generation inhibitors.

Pharmacokinetic studies show that nilotinib reaches peak plasma concentration within 2–4 hours after oral intake. It is metabolised primarily by CYP3A4 in the liver, and the terminal half‑life averages 15–17 hours, allowing twice‑daily dosing. Steady‑state concentrations are typically achieved after 7 days of consistent administration, supporting continuous inhibition of leukemic clones.

Conditions Treated with Tasigna

• Chronic Myeloid Leukaemia (CML) – Chronic Phase – Tasigna is approved for adults who are Ph‑positive and have either failed prior imatinib therapy or are intolerant to it. CML accounts for approximately 15 % of adult leukaemias in Hong Kong, with an estimated incidence of .7 per 100 000 population per year. Early and effective control of BCR‑ABL activity is critical to prevent progression to accelerated or blast phase.

• CML – Accelerated Phase – For patients whose disease shows additional cytogenetic abnormalities or rising BCR‑ABL transcript levels despite first‑line treatment, nilotinib offers a more potent inhibitory profile.

• CML – Blast Crisis (as part of combination therapy) – While not a standalone curative regimen, tasigna may be incorporated with chemotherapy or allogeneic stem‑cell transplantation to achieve deeper molecular responses before definitive therapy.

These indications are supported by phase III trials (e.g., ENEST1st, ENESTnd) that demonstrated superior rates of major molecular response (MMR) and lower progression risk compared with imatinib.

Who is Tasigna For?

Tasigna is appropriate for adult patients (≥ 18 years) who:

• Have confirmed Philadelphia‑chromosome‑positive (Ph +) CML in chronic, accelerated, or blast phase.
• Have demonstrated intolerance to imatinib (e.g., severe myelosuppression, persistent oedema) or have documented resistance due to BCR‑ABL kinase‑domain mutations that remain sensitive to nilotinib (e.g., Y253H, E255K).
• Possess adequate hepatic function (Child‑Pugh A) and moderate renal function (eGFR ≥ 30 mL/min/1.73 m²).

Tasigna is not recommended for:

• Pregnant or breastfeeding women, because teratogenic effects have been observed in animal studies.
• Patients with severe cardiovascular disease (e.g., recent myocardial infarction, uncontrolled angina) due to an increased risk of arterial thrombosis.
• Individuals taking strong CYP3A4 inducers (e.g., rifampicin, carbamazepine) that could markedly lower plasma concentrations.

Clinical judgement, based on disease phase, comorbidities, and prior therapy, determines whether nilotinib is the optimal choice.

Risks, Side Effects, and Interactions

Common

• Rash – mild to moderate maculopapular eruptions, often manageable with antihistamines.
• Pruritus – itching without visible rash, frequently associated with dry skin.
• Elevated lipase/amylase – may indicate subclinical pancreatitis; regular monitoring recommended.
• Musculoskeletal pain – arthralgia or myalgia, typically transient.

Rare

• Hyperglycaemia – increased fasting glucose observed in a minority of patients; consider periodic HbA1c testing.
• **QT interval prolongation – electrocardiogram (ECG) changes that can predispose to arrhythmia; more common in patients with electrolyte disturbances.
• Peripheral arterial disease – progressive arterial occlusion reported in long‑term follow‑up; assess peripheral pulses annually.

Serious

• Severe hepatotoxicity – marked elevation of transaminases (ALT/AST > 5 × ULN) requiring temporary discontinuation.
• Life‑threatening pancreatitis – abdominal pain with high lipase/amylase; immediate drug cessation advised.
• Arterial thrombosis (e.g., myocardial infarction, stroke) – occurs more frequently in patients with pre‑existing cardiovascular risk factors.

Drug–Drug Interactions

• Strong CYP3A4 inhibitors (ketoconazole, clarithromycin) increase nilotinib exposure → dose reduction or avoidance.
• Strong CYP3A4 inducers (rifampicin, phenytoin) reduce exposure → may lead to therapeutic failure.
• Proton‑pump inhibitors (omeprazole, esomeprazole) decrease absorption when taken within 2 hours of tasigna → separate dosing by at least 2 hours.
• Anticoagulants (warfarin, direct oral anticoagulants) may have altered efficacy; monitor INR or relevant clotting parameters closely.

Patients should provide a full medication list, including over‑the‑counter supplements, to the prescribing physician.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – 400 mg orally twice daily (total 800 mg per day) taken on an empty stomach (at least 2 hours before or 1 hour after a meal). Dose adjustments are required for hepatic impairment (reduce to 200 mg twice daily) or for patients unable to tolerate the full dose.

• Missed dose – If a dose is missed by less than 6 hours, take it as soon as remembered. If more than 6 hours have elapsed, skip the missed dose and resume the regular schedule; do not double‑dose.

• Overdose – Symptoms may include severe nausea, vomiting, diarrhoea, and dizziness. Immediate medical evaluation is essential. Supportive care, gastric lavage, and activated charcoal are recommended per local toxicology guidelines.

• Food and alcohol – High‑fat meals markedly reduce nilotinib absorption; patients should avoid taking tasigna with fatty foods. Alcohol can exacerbate hepatotoxicity and should be limited.

• Comorbidities – Patients with diabetes, hypertension, or dyslipidaemia require routine monitoring because nilotinib can affect glucose metabolism and lipid profiles.

FAQ

• Is Tasigna covered under Hong Kong’s public health insurance schemes?
  Some patients may receive partial reimbursement through the Chronic Disease Management Programme if their specialist documents medical necessity. Coverage varies by individual eligibility and requires prior authorization.

• Can tasigna be stored in a refrigerator?
  No cold storage is required. Tasigna should be kept at controlled room temperature (15‑30 °C), protected from excess heat, humidity, and direct sunlight.

• What does the tablet look like?
  Tasigna tablets are white to off‑white, film‑coated, and marked with “400 mg” on one side. Generic nilotinib tablets may differ in imprint but are identical in size, shape, and strength.

• Are there differences between the US and EU formulations of nilotinib?
  The active ingredient and approved dosage are the same, but excipients (inactive ingredients) can vary slightly. These differences are not clinically significant for most patients but may affect tolerability in rare cases of hypersensitivity.

• How should I travel with tasigna?
  Carry the medication in its original packaging with the prescription label visible. Declare it at customs if required and keep it in hand luggage to avoid temperature extremes in cargo holds.

• What laboratory tests are needed while on tasigna?
  Baseline and periodic monitoring of complete blood count, liver function tests, fasting lipid profile, fasting glucose/HbA1c, and ECG for QT interval are recommended. Serum lipase/amylase should also be checked if abdominal symptoms develop.

• Can tasigna be taken with herbal supplements such as St John’s wort?
  St John’s wort is a strong CYP3A4 inducer and can lower nilotinib plasma levels, potentially reducing efficacy. Patients should avoid such supplements unless a physician advises otherwise.

• Why does tasigna require an empty‑stomach regimen?
  Food, especially high‑fat meals, reduces nilotinib absorption by up to 50 %. Taking the drug on an empty stomach ensures consistent plasma concentrations and optimal therapeutic effect.

• Is there a risk of drug testing false positives with tasigna?
  Nilotinib is not included in standard occupational drug‑screening panels, and no known metabolites cause false‑positive results for common illicit substances.

• What are the latest clinical trial results for nilotinib?
  The ENESTnd trial (5‑year follow‑up) showed a 55 % major molecular response rate for nilotinib 400 mg twice daily versus 31 % for imatinib, with significantly lower progression to accelerated or blast phase. Ongoing studies are evaluating combination regimens with interferon‑α and newer BCR‑ABL inhibitors.
